Definitions
- This invention relates to the processing of raw poultry by which the poultry product is prepared for human consumption. More particularly, this invention relates to a method and apparatus for separating poultry parts, such as separating the back from the thighs of the birds in a continuous fully automated process.
- the parts be accurately separated from one another so that bone chips or fragments are not formed during the separating process and are not found in the separated parts. Further, it is desirable that the separating functions be performed in a rapidly operating automated system which accurately separates the parts from one another.
- the overhead conveyor system in poultry processing plants, whereby the birds are suspended from an overhead conveyor system in an inverted attitude, with the legs of the bird supported in shackles that are carried by the conveyor system.
- the shackles move the birds through one or more processing stages, such as a vent cutter, a bird opener, an eviscerator, a neck breaker, a lung puller, and a crop remover. Further, the birds can be moved through various parts separating devices so that the carcasses are subdivided into, for example, separated breasts, backs, wings, legs and thighs.
- the present invention comprises an apparatus for removing backs from the saddle of previously cut poultry carcasses as the poultry carcasses are moved along a processing path suspended invertedly by their legs from an overhead conveyor.
- the apparatus comprises a gripper member for gripping the back portion of a poultry carcass suspended by its legs and which is adapted to proceed along a closed conveyor loop at a higher speed than that of the overhead conveyor, and a guide means is provided which guides the back portion of the carcass in a portion of the closed loop until after the back has been removed from the thighs.
- Tearing the legs and thighs loose from the back of the carcass saddle is effected as the back of the carcass is moved between a large chain wheel incorporated in the closed conveyor loop and the guide means.
- the legs and thighs remain supported by the moving shackles of the overhead conveyor and proceed along the processing path of the overhead conveyor as the back is gripped by the gripper member and begins a downward arcuate movement away from the legs.
- the gripper member which engages and controls the movement of the back of the carcass comprises a conveyor chain with outwardly projecting pins which clutch and positively move the back of the bird at a faster rate of movement than the legs and thighs along a path that first is substantially parallel to the path of the legs and later diverges from the path of the legs.
- the processing station preferably comprises means to center the poultry and to guide it along the blades.
- the centering means comprises a fork that is cantilevered on a blade-carrying plate and an enlarging, suspended centering valve at its upstream end for centering poultry of different sizes as the poultry enters the processing station.
- the guide means can comprise guide rails for aligning poultry with the processing station and a generally V-shaped guide plate for straddling the center of the back portion of the carcass.
- the blade-carrying plate can simultaneously serve as support for two pairs of fixed upper blades that operate between the back portion and the legs of the poultry carcass, and one pair of pivotably disposed lower blades that determine the external tear lines between the back portion and the legs of the carcass, the distance between the two upper blades on either side of the blade-carrying plate being bridged by a portion of the guide plate.
- the first pair of fixed blades preferably comprises thin blades that cut up to the thigh bone, so that the joint can be unfolded. This unfolding is effected as the pointed chain conveys the back portion faster than the shackle conveyor moves the legs so that the joints are tensioned and the ball joint of the thigh tends to leave its socket.
- the edges of the guide rails enter this initial cut, and the guide rail edges "seek" out the gap of the joints so that the second pair of blades can cut precisely between the bones of the joints.
- These two blades are sturdier than the first blades, so that they can cut the muscles that retain the joint and those around the joint, so that the thigh is detached from the back portion.
- the pivotably disposed lower blades are preferably loaded or biased toward their respective cutting positions, e.g., by means of weights, to allow the blades to cut through muscle and tissue but to pivot as they contact the bone to avoid cutting the bone.
- the apparatus shown in Fig. 1 has a frame of which only one of the columns 1 has been shown.
- a horizontal blade-carrying plate 2 is connected to this column 1, which plate is parallel to an overhead conveyor 3 with hooks 4.
- a fork 5 is disposed to which is pivotably mounted an enlarging, suspended centering guide or valve 6 at its upstream end.
- the hooks 4 are continuously moved from the left to the right in Fig. 1 by the conveyor 3.
- the end of the centering guide has such a triangular shape that it lies in the extension of the guide plate 12 disposed under the bearing plate 2 in the position moved upwards by the poultry carcass.
- the centering guide ensures that the back portion 8 internally properly engages the guide plate 12.
- the poultry portion to be processed is now properly centered and subsequently enters the actual processing station 13.
- the processing station 13 has advancement means including a chain 16 that extends over a small chain wheel 14 and a large chain wheel 15 in a vertical plane, which chain has outwardly projecting pins 17.
- the pins 17 centrally engage the outer side of the back portion 8 and convey this at a speed higher than the speed of the conveyors 3, so that the joints are tensioned.
- the processing station 13 furthermore comprises the before-mentioned guide plate 12 that also extends around the large chain wheel 15 in circle sector shape and thus ensures that the back portion 8 remains in the closed loop of the gripper member 16 when it is torn loose from the legs 7, after which the back portion is released at the bottom of the processing station.
- a first pair of fixed blades 19 comprise thin, relatively weak blades that cut up to the thigh bone as schematically shown in Fig. 8, so that the joints, comprising a ball 20 and a cup 21, can be unfolded.
- These first blades 19 are disposed in corner pieces 23 that have been arranged adjustably over the width with bolts 24 on a first transverse part 25 that is connected to the blade-carrying plate 2.
- a second pair of fixed blades 26 comprise relatively strong, pointed blades that cut the muscles around the exposed joints 22 visible in Fig. 8. These second blades 26 have been disposed adjustably and exchangeably in blade retainers 27 that have been mounted with bolts 28 on a second transverse part 29 that is connected to the blade-carrying plate 2.
- a pair of lower blades 31 is pivotably disposed about a horizontal shaft 30 that score the poultry to determine the external tear lines between the back portion 8 and the legs 7.
- a rod 32 bent in an S-shape is welded to each of the shafts 30, onto which rod weight can be slid and fixed so as to determine the cutting force.
- the weights 33 are also possible to replace the weights 33 with springs.
- Figs. 6 and 7 show the invention in another preferred form in which the weights 33 are replaced with pneumatic cylinders 41.
- a pair of blade carrying members 42 are pivotably mounted about pivot pins 43.
- One end of each member 42 carries a lower blade 31 with the other end pivotably coupled to the pneumatic cylinder 41 by means of a ball and socket arrangement 44. So constructed, air pressure may be supplied to the cylinders to bias the lower blades with a selected force.
- the rod of each cylinder When the cylinders 41 are charged with air, the rod of each cylinder is retracted so as to pivot the blades 31 toward the direction of the oncoming birds. When a bird engages the cutting blades 31, these blades tend to cut the exterior skin and meat at the joints between the back and the thighs of the birds, tending to separate the backs from the thighs.
- the air charged cylinders 41 permit the blades 31 to pivot in the direction of movement of the birds so that the blades will not tend to cut through the bone at the joints of the birds, but will pivot so as to cause a slicing action with respect to the meat of the bird and cut around the joints.
- Figs. 5-7 show a rotary disc cutter 37 which is movably mounted for movement between a raised position and a lowered position.
- the disc cutter 37 is powered by the small chain wheel 14 via chain 38.
- the disc cutter is mounted to a housing 39 which is pivotably mounted at one end about an axis extending through the small chain wheel 14. The other end of the housing is releasably secured to the framework by means of a bolt 40 having a quick-release handle.
- a pair of guide protrusions 46 are mounted to the blade carrying plate 2 and extend downwardly on either side of the blade carrying plate. As a poultry back portion passes the guide protrusions 46, the protrusions tend to seek the joint between the back and thighs of the poultry to guide the joints toward the first cutter blades 19.
- the back portion 8 which was originally directed downwardly, is accelerated relative to the legs and rotates relative to the legs.
- the back portion thereby begins to tear loose from the legs 7 precisely at the location of the large chain wheel 15.
- the back portion is thus more or less torn off by the chain 16 and the guide plate 12, after incisions have been made in skin and tissue and muscles have been severed in the correct places.
- spreading guide rails 36 extending above the fixed blade pairs 19 and 26, may be employed as well to spread the legs apart somewhat.
- the invented apparatus may employ the movably mounted circular blade or disc cutter 37 disposed between the centering guide 6 and the chain 16, as seen in Figs. 5-7.
- the circular blade 37 When the circular blade 37 is in the elevated position, the above-described special working of the apparatus to remove the legs is ruled out.
- An apparatus according to the present invention has the advantage of being capable of being added to an existing conveyor line, without the necessity of rehanging the poultry on a separate conveyor.
Abstract
Description
- This invention relates to the processing of raw poultry by which the poultry product is prepared for human consumption. More particularly, this invention relates to a method and apparatus for separating poultry parts, such as separating the back from the thighs of the birds in a continuous fully automated process.
- When previously eviscerated poultry carcasses are to be cut into parts, it is desirable that the parts be accurately separated from one another so that bone chips or fragments are not formed during the separating process and are not found in the separated parts. Further, it is desirable that the separating functions be performed in a rapidly operating automated system which accurately separates the parts from one another.
- In recent years, more extensive use has been made of the overhead conveyor system in poultry processing plants, whereby the birds are suspended from an overhead conveyor system in an inverted attitude, with the legs of the bird supported in shackles that are carried by the conveyor system. The shackles move the birds through one or more processing stages, such as a vent cutter, a bird opener, an eviscerator, a neck breaker, a lung puller, and a crop remover. Further, the birds can be moved through various parts separating devices so that the carcasses are subdivided into, for example, separated breasts, backs, wings, legs and thighs.
- It has been known in the art to cut the legs from the back portion with rotary blades as the poultry is moved along the overhead conveyor. As a consequence of this manner of cutting, part of the peritoneum and some fat may be left on the legs, whereas the so-called oysters are often partially or entirely left on the back portion. For quality's sake, the opposite result should be achieved.
- Briefly described, the present invention comprises an apparatus for removing backs from the saddle of previously cut poultry carcasses as the poultry carcasses are moved along a processing path suspended invertedly by their legs from an overhead conveyor. The apparatus comprises a gripper member for gripping the back portion of a poultry carcass suspended by its legs and which is adapted to proceed along a closed conveyor loop at a higher speed than that of the overhead conveyor, and a guide means is provided which guides the back portion of the carcass in a portion of the closed loop until after the back has been removed from the thighs. With these provisions the back portion is accelerated with respect to the legs, unfolding the joints between the back and its thighs so that a correct incision can be made into the joints between the back and its thighs. Tearing the legs and thighs loose from the back of the carcass saddle is effected as the back of the carcass is moved between a large chain wheel incorporated in the closed conveyor loop and the guide means. The legs and thighs remain supported by the moving shackles of the overhead conveyor and proceed along the processing path of the overhead conveyor as the back is gripped by the gripper member and begins a downward arcuate movement away from the legs.
- In a preferred embodiment the gripper member which engages and controls the movement of the back of the carcass comprises a conveyor chain with outwardly projecting pins which clutch and positively move the back of the bird at a faster rate of movement than the legs and thighs along a path that first is substantially parallel to the path of the legs and later diverges from the path of the legs.
- The processing station preferably comprises means to center the poultry and to guide it along the blades. The centering means comprises a fork that is cantilevered on a blade-carrying plate and an enlarging, suspended centering valve at its upstream end for centering poultry of different sizes as the poultry enters the processing station.
- The guide means can comprise guide rails for aligning poultry with the processing station and a generally V-shaped guide plate for straddling the center of the back portion of the carcass.
- The blade-carrying plate can simultaneously serve as support for two pairs of fixed upper blades that operate between the back portion and the legs of the poultry carcass, and one pair of pivotably disposed lower blades that determine the external tear lines between the back portion and the legs of the carcass, the distance between the two upper blades on either side of the blade-carrying plate being bridged by a portion of the guide plate.
- The first pair of fixed blades preferably comprises thin blades that cut up to the thigh bone, so that the joint can be unfolded. This unfolding is effected as the pointed chain conveys the back portion faster than the shackle conveyor moves the legs so that the joints are tensioned and the ball joint of the thigh tends to leave its socket. After the cutting action of the thin first pair of blades, the edges of the guide rails enter this initial cut, and the guide rail edges "seek" out the gap of the joints so that the second pair of blades can cut precisely between the bones of the joints. These two blades are sturdier than the first blades, so that they can cut the muscles that retain the joint and those around the joint, so that the thigh is detached from the back portion.
- The pivotably disposed lower blades are preferably loaded or biased toward their respective cutting positions, e.g., by means of weights, to allow the blades to cut through muscle and tissue but to pivot as they contact the bone to avoid cutting the bone.
- The invention will be described in more detail hereafter by reference to the drawings, in which a preferred embodiment of the invention is disclosed.
-
- Fig. 1 is a perspective illustration of a part of an apparatus according to the present invention in a preferred form.
- Fig. 2 is a perspective illustration of the apparatus of Fig. 1, showing first and second blades with pertaining supports on one side of the apparatus.
- Fig. 3 shows a section along the line III-III of Fig. 2.
- Fig. 4 shows a view in the direction of the arrow IV of Fig. 3.
- Fig. 5 is a schematic illustration of a portion of the apparatus of Fig. 1, showing in particular a swiveling disc cutter.
- Fig. 6 is a side elevational view of an apparatus according to the present invention in a second preferred form.
- Fig. 7 is a plan view of the apparatus of Fig. 6.
- Fig. 8 shows, on a larger scale and in perspective, a back portion and two legs of the poultry, in which one of the legs, contrary to reality, has been shown as if loose.
- The apparatus shown in Fig. 1 has a frame of which only one of the columns 1 has been shown. A horizontal blade-carrying
plate 2 is connected to this column 1, which plate is parallel to an overhead conveyor 3 with hooks 4. - At the end of the blade-carrying
plate 2 facing away from the column 1 afork 5 is disposed to which is pivotably mounted an enlarging, suspended centering guide orvalve 6 at its upstream end. - The hooks 4 are continuously moved from the left to the right in Fig. 1 by the conveyor 3. A pair of
chicken legs 7, suspended from a hook 4 and interconnected by a back portion 8 (see Fig. 8), first externally contacts a pair of generally converging guide rails 9 and subsequently internally contacts the suspendedcentering guide 6 that pivots in arecess 10 of thefork 5 about a shaft mounted withscrews 11. - As illustrated in Figs. 1 and 5, the end of the centering guide has such a triangular shape that it lies in the extension of the
guide plate 12 disposed under thebearing plate 2 in the position moved upwards by the poultry carcass. Thus, the centering guide ensures that theback portion 8 internally properly engages theguide plate 12. - The poultry portion to be processed is now properly centered and subsequently enters the
actual processing station 13. - The
processing station 13 has advancement means including achain 16 that extends over asmall chain wheel 14 and alarge chain wheel 15 in a vertical plane, which chain has outwardly projectingpins 17. As thetension chain wheel 18 will not be able to prevent the top part of thechain 16 from sagging, it is recommended to support this chain there (in a manner not shown). Thepins 17 centrally engage the outer side of theback portion 8 and convey this at a speed higher than the speed of the conveyors 3, so that the joints are tensioned. - The
processing station 13 furthermore comprises the before-mentionedguide plate 12 that also extends around thelarge chain wheel 15 in circle sector shape and thus ensures that theback portion 8 remains in the closed loop of thegripper member 16 when it is torn loose from thelegs 7, after which the back portion is released at the bottom of the processing station. - A first pair of
fixed blades 19 comprise thin, relatively weak blades that cut up to the thigh bone as schematically shown in Fig. 8, so that the joints, comprising a ball 20 and acup 21, can be unfolded. Thesefirst blades 19 are disposed incorner pieces 23 that have been arranged adjustably over the width withbolts 24 on a firsttransverse part 25 that is connected to the blade-carryingplate 2. - A second pair of
fixed blades 26 comprise relatively strong, pointed blades that cut the muscles around the exposedjoints 22 visible in Fig. 8. Thesesecond blades 26 have been disposed adjustably and exchangeably inblade retainers 27 that have been mounted with bolts 28 on a secondtransverse part 29 that is connected to the blade-carryingplate 2. - A pair of
lower blades 31 is pivotably disposed about ahorizontal shaft 30 that score the poultry to determine the external tear lines between theback portion 8 and thelegs 7. Arod 32 bent in an S-shape is welded to each of theshafts 30, onto which rod weight can be slid and fixed so as to determine the cutting force. Of course it is also possible to replace theweights 33 with springs. - Figs. 6 and 7 show the invention in another preferred form in which the
weights 33 are replaced withpneumatic cylinders 41. A pair ofblade carrying members 42 are pivotably mounted aboutpivot pins 43. One end of eachmember 42 carries alower blade 31 with the other end pivotably coupled to thepneumatic cylinder 41 by means of a ball andsocket arrangement 44. So constructed, air pressure may be supplied to the cylinders to bias the lower blades with a selected force. - When the
cylinders 41 are charged with air, the rod of each cylinder is retracted so as to pivot theblades 31 toward the direction of the oncoming birds. When a bird engages thecutting blades 31, these blades tend to cut the exterior skin and meat at the joints between the back and the thighs of the birds, tending to separate the backs from the thighs. The air chargedcylinders 41 permit theblades 31 to pivot in the direction of movement of the birds so that the blades will not tend to cut through the bone at the joints of the birds, but will pivot so as to cause a slicing action with respect to the meat of the bird and cut around the joints. - Figs. 5-7 show a
rotary disc cutter 37 which is movably mounted for movement between a raised position and a lowered position. Thedisc cutter 37 is powered by thesmall chain wheel 14 viachain 38. The disc cutter is mounted to ahousing 39 which is pivotably mounted at one end about an axis extending through thesmall chain wheel 14. The other end of the housing is releasably secured to the framework by means of abolt 40 having a quick-release handle. - As shown in Fig. 6, a pair of
guide protrusions 46 are mounted to theblade carrying plate 2 and extend downwardly on either side of the blade carrying plate. As a poultry back portion passes theguide protrusions 46, the protrusions tend to seek the joint between the back and thighs of the poultry to guide the joints toward thefirst cutter blades 19. - If all the
blades chain 16 is also correct, theback portion 8, which was originally directed downwardly, is accelerated relative to the legs and rotates relative to the legs. The back portion thereby begins to tear loose from thelegs 7 precisely at the location of thelarge chain wheel 15. The back portion is thus more or less torn off by thechain 16 and theguide plate 12, after incisions have been made in skin and tissue and muscles have been severed in the correct places. - Due to this optimum processing action, the so-called
oysters 34 remain attached to the legs completely. - What remains is only the
back portion 8 that is unattractive for direct consumption as it mainly consists of bone and fat. Furthermore, theperitoneum 35 now remains attached to theback portion 8. - In order to attain the above result, spreading
guide rails 36, extending above the fixed blade pairs 19 and 26, may be employed as well to spread the legs apart somewhat. - In some cases it is desirable that the
back portion 8 be halved, i.e., cut in the longitudinal direction without removing the legs from the back portion. In order to accomplish this without having to use a different apparatus, the invented apparatus may employ the movably mounted circular blade ordisc cutter 37 disposed between the centeringguide 6 and thechain 16, as seen in Figs. 5-7. When thecircular blade 37 is in the elevated position, the above-described special working of the apparatus to remove the legs is ruled out. - An apparatus according to the present invention has the advantage of being capable of being added to an existing conveyor line, without the necessity of rehanging the poultry on a separate conveyor.
- While the apparatus has been disclosed in a preferred form, it will be obvious to one skilled in the art that numerous modifications, additions and deletions may be made therein, without departing from the spirit and scope of the invention.
